Syncline and anticline are terms used to describe folds based on the relative ages of folded rock layers. A syncline is a fold in which the youngest rocks occur in the core of a fold (i.e., closest to the fold axis), whereas the oldest rocks occur in the core of an anticline. What...
What is the difference between an anticline and a syncline quizlet? Anticlines are folds in which each half of the fold dips away from the crest. Synclines are folds in which each half of the fold dips toward the trough of the fold. You can remember the difference by noting that anticli...
Syncline is a structure in geology in which layers of rock are curved or folded downward with the younger layers of rock at the center of the fold. Syncline folds are caused by tectonics forces throughout the Earth's crust. Answer and Explanation:1 ...

The Yahk River syncline is modelled as a symmetrical fold having an axial depth of 4.2 km to the top of the Upper Aldridge Formation. Collectively, the models outline a broad domal pattern of Moyie sills in the core of the anticline to 12 km depth, supporting a proposal that a gravity ...
The incompetent layers of the Gachsaran Formation escaped from crest to the adjacent syncline. The last seismic profile through the Pazanan anticline (Fig. 6) which cuts across the northwest of this anticline is about 8 km far from the central seismic profile. The deep-seated southwest-ward ...
However, at location 3, on the south-dipping limb of a broad syncline, owing to outcrop size, only the dominant NNW-striking set could be quantified. Crossing relations suggest that the NNW-striking set predates the EW set, like the relative age relationship noted in core from East Painter ...
